Application filed November 17, 1919. Serial Hosanna.

To all whom it may mnrem Be it. known that. I, Mon'rmicn ll. lli's'r, citizen of the United States, residing at Fulton. in the county of ()swego and State of New York. have invented certain new and useful Improvements in Renter Rolls and Bars, of which the following is a specifiention.

This invention relates to heater rolls and bars which are intended for use in healing engines employed to not upon rags. wood pulp or other fihrons stock in the mainline ture of paper;

In the construction of heating engines. n isespecinlly desirable that the fly hairs shall he etl'ertireiv and easily Secured in the roll heads, and it. is :in ohjeet of this invention to produce n roll head. fly bar and securing: means having: parts of special eonstrurtion and arrangement, whereby it is believed the fly burs may he quickly and firmly seem-ed and kept fast. and as expeditiously removed for replacement or repairs.

To illustrate the partieular fornnition and disposition of the parts i-omprising this invention. the tl(.'tlIlIl])2lll \'iH drawings :1 re made :1. part of this application. Figure 1 represents an interior end view of a portion of the roll head to Whirli this invention is applied. Fig. 2 is a top plan view of a portion ol :1 roll head and hat ronstrnrled Fig. 5 is a ton phm view of the wedge. Fig. 4 is n VGI'tlCfl-l erossseetion of the edge on hroken line 4-4ot'l ig.3. Fig. 5 is an end View of a fly hnr constrni-led in aerordnnee with this invention.

Throughout the drawings and desrription the same letter is used to refer to the same part, and in the drawings Figs. 4 and 5 are illustrntii/e of the parts in full size.

Considering the drawings, the roll head A has an annular shoulder a on the inside of the roll head, and it has a. succession of peripheral radially projecting blocks 13 5 need apart leaving recesses 5 between t om.

As best shown in Fig. 2 one wall C of ein-h recess extends perpendicularly across the roll. and the opposite will a diverges and lies across the roll in a. slanting direction. Both walls of the recess incline from the mouth of the recess to the bottom, whereby the bottom of the recess is the widest part thereof. The nnnulnr shoulder a. may he or,

ranged flush with the bottoms of the reeesses. Both sides of head A may have a shouldor.

As best set out in Fig. 5, the fly bar D has the tint side a. and an angular side compriselinations in position or extent as shown in the drawings.

The remaining element or member of the (Ul'tllllllililflll' comprising this invention is the 'wi'dge (l. illustrated in Figs. 3 and 4.

The shoulder f mag be given a 65 The wedge has the top g, the inclined sides H and 1'1, and the bottom J provided with the portion j arranged to en age the shoulder ot' the liar as shown in lg. 1.

In the operation. the fly hair is placed in a recess with its flat side (I niqninst the side wall of the reeess. this wal being the one desel'ihed as extending perpendicularly. :ieross the roll head. It wil be uncle that the wall C inclines from to to both iii! ppoaite wall a, and the meaning of the description of the recess. diverging from t e 0 stating that the wall C extends perpendiculnrly nrross the roll head is that the edge of the wall (1 or any line upon itparallel withi the edge, is perpendicular to the .sides of nib-{"0 0 head. The side of the fly bar having tho shoulder f lies within the recess, and that wall f the recess marked a converges respect to the bar from the inner to ill! outer side of the roll head. ,Both walls of the IKK'GSSGS b incline toward each other from theccnter of the hend and divergo toward the bottoms of the recesses, the bottoms lining the widest parts. Thus, therecesses may he described as wedge-shaped 1M transversely of the head and of dovetail form as shown in Fig. 1. The wed e is in serted between the beveled side a o the fly bar, and the inclined wall of the recess, and the inclined portion j of the bottom of the wedge is arra ed against the shouh der f of the fly bar. s the wedge is driven in, it presses the bar against the side wall 0 me I an the 13 bars is believe to be fiy bsrmay be 'rerhbvetl andrepleced by re the wedga securing it, and that no moviiif speci tools are required erisrm such removal or regalecement. The y bar set out hereinabove' as been described es having one flat side and a doubled beveled side, but, it is not intended to limit this invention to that form.

Havi now described this invention and explaine the mode of its operation, what I claim is 7. q

1. In a heater roll and bar, the combine tion with a roll head having periphcrnl radially projecting blocks spaced abort lesw ing re between them, one sir e wall of each of the said were being inclined from the month of the recess whereby the bottom of the recess is the widest pm thereof the said re being wider on one side oi the roll head, of fly bars each having at beveled side and a longitudinal shoulder terminatan% a wedge constrnctedto en a e the said inclinedwall of the recess an t e beveled ide of the fly bar, the bottom of the wedge evin a portion arranged to engage the said shoul er of the fly bar.

2. In a. beater roll and bar, the combination with a roll head having peripheral radially projecting blocks spaced a art leavmg recesses between them, one sir e wall of each recess extending rpendieolsrly across the head and one o the wells extending siantingly across the head one of the side walls of each recem being inclined from the mouth of the recess whereby the bottom of the recess is the widest 'art thereof, of fly bars each havin a have ed side and a longitudinal shoul er terminating said beveled side at its lower ledge-1, and s wedge constructed to engage the said inciined wali of the recess and the said beveled side of the fly bar, the said wedge having a portion con the said beveled side- 'at its lower edge tien with a roll head having peripheral; radially projecting blocks spaced :1 ertleaving recesses between them, one o the saidwails of each recess extending perpendiculsrly across the head, both of the side Walls of each recess being inclined from the mouth of the recess whereby the bottom of the re cess is the widest part thereof, the said walls oi the recess converging toward each other across'the head from the inner to the outer side thereof, of fly bars each having a beveied side and a longitudinal shoulder ter- "minating the said beveled side at its lower edge, and s wedge constructed to on age the inclined walls of the recess and the "v eled side of the fly her, the said wed e haw.

in e rtion'arranged to enga e t esaid sli uld i' ofi'the fiy bar. g

4. In a heater roll and bar, the combination with a roil heed having peripheral radially projecting blocks spaced a art leaving recesses between them, one we 1 of each recess being inciined from the mouth of the recess whel-eh' the bottom of the recess is the Widest part t creof, cffiy bars each having it b veled side and a longitudinal shoulder ter ineting the acid beveled side, and a wedge arranged to engage the said inclined well of the recess'anld the beveled side of the fly bar and the said shoulder of the fly bar, the said sidewall of the recess and the beveled side of the By her being formeddL vergently with respect to each other.

5. In a heater roll and bar, the combination with a roll head having transverse wedge-shaped and dovetail recesses and an annular internal or external shoulder, of fly bars resting upon the said annular shoulder or upon the bottom of there'cess, and each wedg shaped and dovetail recesses and an annular shoulder, of fly bars resting upon the said shoulder and each fly, bar being rovided with a side having a longitudinal shoulder, and a wedge on a ing the side or the recess end the side of the shoulder of the bar.

T. In a heater roil and bar, thecosnbination. ot a roll head having slots or recesses for fly bars with the side walls so inclined that the said slots or recesses are wider at the bottom than at'the outer periphery of the roll head, one side wall of each recess or slot being at ri ht angles to the ll head, or in other wor s, in a plane Whig is parallel to the axis ofv hgi 'roll, the other side wall of each said recess extending slantmgly across th roll head or in a plane which 1s at an angle to the axis of the roll,

ar and the seid l said angle being such as to make the slot thus formed wider at one side of the roll head than at the other side, and fly bars having a longitudinal shoulder at the lower edge, and wedge constructed to engage the said inclined walls of the slots or recesses as well as the side and shoulders of the fly bars,

whereby the bars are forced against an annular ring. or against the bottom of the slots or recesses, and against the said parallel side 10 wall of the recesses.

In testimony whereof I aflix my signature.
